RADIATOR SHOCK-ABSORBERL Specification of Letters Patent.

Patented Dec. 7, 1915.

. Application filed January lt), 1915. Serial No; 3,064.

To all whom it may concern:

Be it known that I, GUSTA" A. LIND- STROM, a citizen of the UnitedStates, residing at Menominee, 1n the county of Menoml- 5 nee and Stateof Michigan, have invented absorbers, and its object is to provide meansindependent of the usual springs of an automobile pleasure car or truck,by which the radiator will be specially cushioned against jolts and jarsduring the progress of the vehicle.

cooling water of the system is directed to be cooled by the passage ofair from the outside about the tubes. In a great many factories theradiators are put together with tin solder, which does not wellwithstand 5 vibrations'and repeated shocks, and frequently breaks withresulting leaks in the radiator joints. On most motor trucks known tothis applicant the vibrations are greater than on pleasure cars, asrelatively stiff springs and solid tires are customarily used. Theshocks, jolts and twists to which the radiator are subjected are verysevere on trucks, and even on the best cars there is an unavoidable andlong continued vibration that has its harmful effect upon the radiator.

In the accompanyin ferred construction 0 illustrated.

Figure 1 is a front view of a radiator to which this invention has beenapplied. Fig. 2 is an external side view, and Fig. 3 is a verticalsection upon the broken line w-.'r of Fig. 2, and showing a portion of aradidrawings the prethis invention is ator attached. In Figs. 2 and 3the scale of drawing has been increased to show all parts assembled.

Throughout the description and in the drawings the same letter is usedto refer to the same part.

explanation of the parts and their arrangement in one will answer forboth.

The radiator bracket a supports the foot of the post B, which is usuallyof the bifurcated shape indicated by the broken lines in Fig. 2. At thetop the post has a clamp b and a clamping screw C. The clamp holds thestud D of the upper shell (Z of a .casing, of which the lower shell orpart is marked E. The shells are suitably threaded and joined asillustrated in Fig. 1. The

casing is thus connected with the radiator Ar The bottom of the lowershell E of the casing has a central opening 6, and upon the bottominteriorly is a compressible washer F, usually of felt. \Vithin thecasing is the cup G that has a lower annular shoulder g resting upon thewasher F. The cup G carries the pneumatic cushion or ball H upon whichthe casing rests, and the cup has a shank-or cylindrical portion Jextending downwardly through the washer F, and secured by the screw J tothe angle bracket K, which is in its turn secured to the side piece Lof-the frame of a truck or automobile. The cup 9 is, therefore, asupport for the pneumatic cushion and is connected with the frame.

In the operation of this invention, the vibrations of the frame due tothe running of the motor are almost entirely absorbed by the rubber ballor air cushion 'H. In practice it is found that the tremor of theradiator and hood ordinarily so pronounced and noticeable in manymachines while the motor is acting, may be damped by the use of thisinvention properly applied to such an extent as to render the radiatorjoints practically safe from injury.

When the automobile is proceeding, an

-upward jolt of the frame compresses the ball H between the upper shelld of the casing and the cup G. The casing as a whole moves relativelydownwardly and the shoulder 9 and the washer F may be for a momentseparated. As the ball H reacts and the radiator is thrown upwardly, thefelt washer limits its rise and takes up the jar.

It is thought to be clear that an experi: enced and skilful mechanicianmay vary the forms of the parts of this invention from thoseillustrated, and this invention is not restricted narrowly thereto.

When an automobile is in use there are produced frequent lateral shocksto which the radiator is subjected. To absorb such shocks the pneumaticcushion is given such form as to enable it to roll sidewise in anydirection. The ball H will so move in the cup G. It is believed to bediscernible from anfinspection of Fig. 3 that a sidewise movement of theradiator and casing will comof the cup is smaller in diameter. than the.opening e'in the bottom of the lower shell E. That construction allowsthe radiator and the attached casing, andthe frame L carrying the cup tomove one with respect to the other to a certain extent in any directionhorizontally. Or, the cup and casing may turn somewhat one with' respectto the other. As the ball has a free rolling movement in the cup and incontact with the casing, it interposes a cushioning effect whether theshock be vertical orhorizontal or both together.

Having now described this invention, and explained the mode of claimis 1. In a radiator shock absorber, the combination with a radiator, ofa vehicle frame,

a casing secured to the radiator, the said casing comprising upper andlower shells, means for removably securing the said shells together, thesaid lower shell having an opening in its bottom, a cup located withinthe said shell and having a portion passing downwardly through theopening in the bottom of'the said lower shell and secured to the saidvehicle frame, and an elastic ball located within the casing andarranged to support the said casing, the said ball havmg a free rollingmovement in any direcits operation, what I ball located within thecasing in rolling contact with the top thereof, a. cup. constructed tosupport the ball movably and arranged within the casing, the said casinghaving an opening in its bottom, the

said cup having a portion passing through the said opening, means forconnecting the said portion of the cup with the said vehicle frame, andcollapsible means arranged between the cup and the bottom of the casingwithin the casing for cushioning the relatively downward movement of thecup.

3. In a radiator shock absorber, the combination with a radiator, of avehicle frame, a casing connected with the said radiator,

the said casing having an opening, an elastic ball located within thecasing in rolling contact with the top thereof, a cup constructed tosupport the ball movably and arranged within the casing, the said cupbeing less in diameter than the interior of the casing and having arelatively vertical movement and a relatively horizontal movement in anydirection with respect to the said casing, and means extending throughthe said opening in the casing for connecting the said cup and thevehicle frame.v

In testimony whereof I affix my signature in presence of two witnesses.
